Automatic dispensing device

Abstract

An automatic dispensing device is provided with a sample container holder having a plurality of recesses, each of the recessed being configured to accommodate a sample container, a biasing member provided in each of the plurality of recesses, the biasing member being configured to bias the sample container accommodated in the recess upward, and a liquid dispensing mechanism having a discharge pipe for discharging a liquid from a tip end, the liquid dispensing mechanism being configured to discharge the liquid in a state in which the tip end of the discharge pipe is pressed against an inner part of the sample container at a predetermined dispensing target position from above.

1 . An automatic dispensing device comprising:
 a sample container holder having a plurality of recesses, each of the recesses being configured to accommodate a sample container;   a biasing member provided in each of the plurality of recesses, the biasing member being configured to bias the sample container accommodated in the recess upward; and   a liquid dispensing mechanism having a discharge pipe for discharging a liquid from a tip end, the liquid dispensing mechanism being configured to discharge the liquid in a state in which the tip end of the discharge pipe is pressed against an inner part of the sample container at a predetermined dispensing target position from above.   
     
     
         2 . The automatic dispensing device as recited in  claim 1 ,
 wherein the liquid dispensing mechanism is configured to discharge the liquid after lowering the tip end of the discharge pipe by a predetermined distance from a predetermined initial position above the sample container.   
     
     
         3 . The automatic dispensing device as recited in  claim 1 ,
 wherein the biasing member is configured to come into contact with the sample container from below.   
     
     
         4 . The automatic dispensing device as recited in  claim 1 ,
 wherein the sample container holder is configured to hold a container as the sample container including a filter, the sample container having an upper space and a lower space partitioned by the filter, and   wherein the dispensing target position is a position on an upper surface of the filter equipped by the sample container accommodated in each of the plurality of recesses.   
     
     
         5 . The automatic dispensing device as recited in  claim 1 ,
 wherein the sample container holder is a temperature controller provided with a heat transfer block and a heater for heating the heat transfer block, and   wherein the plurality of recesses is provided on an upper surface of the heat transfer block.   
     
     
         6 . An automatic dispensing device comprising:
 a sample plate holder configured to hold a sample plate in which a plurality of sample holding areas is formed;   a biasing member provided at a position corresponding directly below each of the plurality of sample holding areas of the sample plate holder, the biasing member being configured to bias the sample plate upward; and   a liquid dispensing mechanism provided with a discharge pipe for discharging a liquid from a tip end, the liquid dispensing mechanism being configured to discharge the liquid in a state in which the tip end of the discharge pipe is pressed against a part of the sample plate corresponding to each of the plurality of sample holding areas from above.
